Histogenics Closes $49 Million Series A Fundraising to Support
Commercial Development of Transformational Cartilage Repair Products

WALTHAM, Mass.--(BUSINESS WIRE)--Regenerative medicine company Histogenics Corporation, announced today
the completion of a $49 million round of financing. The syndicate was
led by Sofinnova Ventures with participation from additional new
investors Split Rock Partners, BioMed Ventures and FinTech GIMV Fund,
L.P. Existing investors ProChon Holdings BV, Altima Partners, Foundation
Medical Partners, Inflection Point Capital and Boston Millennia Partners
also participated in the financing. Proceeds will be used to complete
the ongoing Phase 3 clinical program for lead product candidate NeoCart®,
which is currently enrolling patients. NeoCart is an autologous
neocartilage tissue implant that utilizes the patient’s own cells to
regenerate cartilage in patients suffering from cartilage lesions in the
knee. Funds will also support efforts to obtain regulatory clearance in
the European Union for product candidate VeriCart™, a single-step,
cell-free collagen scaffold uniquely designed to be used in conjunction
with the patient’s own stem cells, to repair small cartilage defects
frequently observed in meniscal and anterior cruciate ligament repair
procedures. Garheng Kong, MD, PhD of Sofinnova Ventures and Josh
Baltzell of Split Rock Venture Partners will join Histogenics’ Board of
Directors. Arnold Freedman of Boston Equity Advisors served as the
exclusive placement agent.

Patrick O’Donnell, President and Chief Executive Officer of Histogenics,
commented, “We believe the quality of the investors and the significant
level of commitment demonstrated in this financing speak to the
potential of our product candidates to transform the treatment of
cartilage injury with the goal of returning patients to their pre-injury
level of activity. Each year, 1.8 million active adults and elite
athletes undergo arthroscopy for the diagnosis and treatment of painful
cartilage defects in the knee. With continued positive clinical results,
we believe our Phase 3 product candidate, NeoCart, has considerable
potential as a much-needed treatment alternative for a significant
portion of these patients. The successful completion of this financing
fully funds the Company to reach key clinical and commercial milestones
for NeoCart and VeriCart and allows us to focus our full attention on
continued successful clinical and regulatory execution.”

Garheng Kong, MD, PhD, General Partner of Sofinnova Ventures added,
“NeoCart has the potential to dramatically change the way knee cartilage
injuries are treated. Current treatments for knee cartilage damage
frequently do not produce the lasting effects that individuals need to
avoid serious knee pain and improve function—preventing them from
getting back to their active, daily lives. Published data have shown
that patients treated with NeoCart experienced a very durable response
that is sustained throughout a period of four years or more. Sofinnova
is pleased to support Histogenics’ efforts to receive approval for
NeoCart and address this unmet clinical need.”

About NeoCartNeoCart® is an autologous
bioengineered neocartilage grown outside the body using the patient’s
own cells for the regeneration of cartilage lesions. NeoCart recently
entered a Phase 3 clinical trial after reporting positive Phase 2 data,
in which all primary endpoints were met, and NeoCart was found to be
generally well tolerated.

About VeriCartVeriCart™ is a single step, off-the-shelf,
cell-free collagen scaffold, specifically designed for cartilage
applications, which when reconstituted with the patients own bone marrow
or augmenting marrow stimulation procedures, is intended for the
improved repair of cartilage tissue. VeriCart is currently in
development.

About HistogenicsHistogenics is a leading regenerative
medicine company that combines cell therapy and tissue engineering
technologies to develop highly innovative products for tissue repair and
regeneration. In May of 2011, Histogenics acquired Israeli cell-therapy
company ProChon BioTech. Histogenics’ flagship products focus on the
treatment of active patients suffering from articular cartilage derived
pain and immobility. The Company takes an interdisciplinary approach to
engineering neocartilage that looks, acts and lasts like hyaline
cartilage. It is developing new treatments for sports injuries and other
orthopedic conditions, where demand is growing for long-term
alternatives to joint replacement. Histogenics has successfully
completed Phase 1 and Phase 2 clinical trials in which the NeoCart
autologous tissue implant’s effectiveness is compared to that of
standard microfracture surgery. Based in Waltham, Massachusetts, the
company is privately held. For more information, visit www.histogenics.com.
